This is not a good faith argument. Nobody needed nutritional science to tell them a malnourished mule didn't do mule things very well, physics to tell them water flowed downhill, etc. People of the past believed in witches and superstition for things their senses, experiences and intuition could not explain. Likewise the achievements in science have mostly been in explaining what we can't observe with human hardware. For example replacing miasma theory with germ theory, understanding and harnessing electromagnetism, etc.
